12 + x = -12 + 3x
12 + x = 3x - 12
12 = 3x - 12 - x
12 = 2x - 12
12 + 12 = 2x
24 = 2x
x = 24/2
x = 12

B; 25.65+13.23+6.35=45.23

To do this mentally just add the 2 decimals places together first (1.23). Then just add the whole numbers (44). Then add the 2 numbers together, 44+1.23=45.23

Naya [18.7K]
First let’s call the square shape A and the rectangle shape B.

To find the area of shape A you do 24 x 24 = 576cm squared

To find the area of shape B you do 40 x 24 = 960cm squared

To find the total area you just add the two areas together
576 + 960 = 1536cm squared
